Yokohama Rubber Co., Ltd., PRGR Primage, founded in 1983, is a subsidiary of Yokohama Rubber Co., Ltd. in Japan, and is the leading golf brand in Japan's sales list

The full name of PRGE is Pro Gear. Its parent company is also Yokohama Rubber, a well-known Japanese rubber company. The feature of this product is that it is mainly for ordinary golfers, and the product is designed to be lightweight. The design of the ball is average, and the design is not too distinctive, but the product quality is considered to be at a high level.

PRGR IS YOKOHAMA RUBBER CO., LTD. LTD JAPAN). Founded in 1917, Yokohama Rubber is now the world's seventh-largest tire manufacturer with an annual turnover of about 400 billion yen and a history of 91 years, mainly consisting of tires, industrial rubber, and sports businesses.

In 1983, Yokohama Rubber established Sports Complex Co., Ltd. and began to produce golf clubs under the PRGR brand, which became a well-known golf brand in Japan within a few years thanks to its innovative technology and meticulous craftsmanship.

Golf Contribution:

Pioneered the concept of "starting ball speed".

PRGR's greatest contribution to golf clubs is the introduction of scientific quantitative criteria for consumers in the selection of clubs. In the 1980s, the average club manufacturer used the letters "X", "S", "R" to identify the hardness of the club, and there was no uniform rule between the manufacturers, and the standards defined were not equal, so that customers were confused when choosing a club. Therefore, at the beginning of its establishment, PRGR used the scientific method to repeatedly verify and define the "starting ball speed" based on the hitting speed and used it as the criterion for selecting clubs. Since then, the hardness of PRGR clubs is determined by the swing speed "m/s", and when golfers select clubs, they can use speed measuring instruments and professional software to measure the speed of the club, the angle of the ball and the amount of rotation of the ball, so as to grasp the swing pattern of the player, and the obtained values can help the golfer choose the right style and hardness to use. The introduction of the concept of "starting ball speed" has made the choice of club away from the old way of empirical guessing, and has become a scientific matter. Since then, this value has become the standard adopted by the golf industry.

Hardcore Revolution

Until 1984, cutout design was the mainstream of hardcore. Because its manufacturing cost and production technology are lower than those of hollow manufacturing, general manufacturers use hollow casting. PRGR is the only one that firmly believes in the advantages of hollow design: "high reflexivity, high ballistics, and easy handling". Under the conditions of high development cost and technical difficulties, we insisted on manufacturing irons with a hollow design. Launched in 1984, the 500 Series broke with the tradition of the global golf industry of creating a hollow design for professional players. Twenty years later, the 900 series was launched, and by this time, hollow design irons were already commonly used by professional players. The 2004 910 TR-X was made of tungsten alloy and made of ultra-low center of gravity irons, which is still used by Japanese professional Shoji Ozaki. Since then, the 2005 915CR and 925CR have become even more beautiful, reflecting PRGR's spirit of continuous breakthrough and innovation.

The first carbon fiber wooden pole

In 1986, PRGR launched the U 240, a groundbreaking driver with a 44-inch length, based on the theory that "the longer the shaft, the faster the ball speed, the farther the distance". At that time, the general driver length was 43 inches, and the size of the clubhead was limited due to the fact that the clubhead was mainly made of persimmon wood and cast iron, and it was very difficult to lengthen the shaft. PRGR, on the other hand, has succeeded in using carbon fiber to make the clubhead, taking advantage of its ultra-light weight to create the first 44-inch shaft driver. In 1989, PRGR re-developed the "U 240 IE" series of drivers, extending the shaft length to the 45-inch form commonly used by manufacturers today. This new technology has established the PRGR brand in the Japanese and international golf market.

Establishment of a universal pole

Today, the so-called "multi-club", "hybrid" or "ironwood" is a popular variety of clubs. PRGR has been a pioneer in club fusion by breaking the mold with tradition in the creation of fairway woods, multi-clubs and irons. ONE OF THE MOST REPRESENTATIVE WORKS IS THE INTEST LX MULTIPURPOSE ROD, WHICH WAS RELEASED IN 1988 AND IS KNOWN AS "TARAKO" (A POPULAR SMALL FISH IN JAPAN) FOR ITS UNIQUE SHAPE. The INTEST LX head is made of a composite of carbon fiber and stainless steel, with a low and deep center of gravity, which solves the problem of difficult handling and low trajectory of the No. 3 and No. 4 long irons that plague many golfers, making the long irons as easy to handle and high trajectory as the mid-irons. INTEST LX IS THUS THE FIRST "UNIVERSAL POLE"

After more than nine years of continuous improvement, ZOOM was introduced in 1996 and established a third class of clubs --- multi-purpose clubs in addition to irons and woods, and the ZOOM I series was further enhanced in 2000.

EVERVERSE WOODS

The Columbian theory emphasized by the PRGR is even more evident with the 1993 REVERSE wooden pole. Previously, the shape of the traditional wooden head was wide at the top and narrow at the bottom, and the center of gravity fell on the center of the shot, but due to the limitations of manufacturing technology, the thickness of the material of the clubhead could not be changed, so the center of gravity position mainly depended on the shape of the clubhead. PRGR has been working this for a long time, and finally broke the traditional shape of the club head with a narrow top and wide bottom on the reverse wood, and moved the center of gravity to the center of the hitting surface. The test results showed that due to the increased accuracy of hitting the center of gravity and the absence of extra spins, the player's swing power was converted into an astonishing flight distance. The successful verification of this theory has become the benchmark of other brands to make clubs, and it has also pushed PRGR to another high edge.

TR DUO is born

Adhering to the concept of REVERSE, PRGR has successively launched three series: H/S BLACK TITANUM, H/S BLUE TITANUM, and H/S red TITANUM, further deepening the previous structure. In the 1990s, the main focus of the service was high reflex, and PRGR developed the SPEAD TITANUM RT and TR-X series. In 2000, the USGA began stipulating that the rebound coefficient of clubs should not exceed 0.83, and PRGR turned to two other important factors in increasing flight distance: the angle of attack and the amount of spin. This is where the DUO series and TR DUO series come in.

In December 2002, PRGR launched a new head structure called TR DUO on the Japanese golf market, successfully creating the world's first composite head driver. The special construction of the TR DUO series wood club head is that the top of the club head is hollowed out and then carbon fiber reinforced plastic (CFRP), which is extremely light and tough, and is a high-end material used in the aviation and aerospace fields. By lowering the center of gravity of the clubhead and increasing the rebound of the clubhead, the PRGR DUO realizes the long-awaited dream of golfers with a high exit angle, high muzzle velocity, and low spin.

In 2005, PRGR introduced the DUO 2 series, which further evolved the composite clubheads.
